I've had a
BlackJack (nope, me neither) BK6000 soldering station for a couple of years. It has a temp controlled soldering iron, hot air gun and desoldering tool, all in one. You can probably get a breadmaking attachment, too (not sure - haven't looked). It's OK, but has a couple of issues.
The desoldering gun looks
identical to the ZD985, with the exception of the cream handle moulding (mine is black, and slightly differently shaped). The replacement desoldering tips include a thin hollow shaft, maybe 60mm long. This fits down through a hole in the heating element, and I guess is in part to transfer the heat to the tip. It also acts as the pipe through which the molten solder is drawn, into the spring-lined reservoir behind. I find that this narrow tube is
VERY prone to blocking. Looks like the end of the tube nearest the reservoir (furthest from the tip) runs cool, and the solder tend to solidify, there. GRR! Much poking with the wire tool (provided), and swearing (not provided).
It's still a useful tool, and MUCH better than a soldering-iron-and-bodge, for anything with two or more legs (which is most things...)
